WAGON -SPRING.

SPECIFICATION forming part of Letters Patent No. 280,858, dated July 10, 1883.

Application filed April 20, 1883. (N model.) 7

boards in which a metallic spring and a spring board are combined to support the body of the vehicle, the object of my improvement being to so construct the combined spring and spring-board that a fricti0n-roller may be combined therewith to avoid the noise and grating sound produced by the adjusting ends of the spring as they slide over the plates at the ends of the board. I p

My invention consists, as will hereinafter be more fully described, in the combination, with a metallic spring and spring-board, of a roller, a roller-track, flanges upon the roller ends adapted to engage with the sides of the rollertrack, and stops up on the latter, with the rollertrack secured to the board, and the under side of the spring, at the ends, constructed to rest upon the rollers.

Accompanying this specification, and forming a part of it, is asheet of drawings contain ing two figures illustrating my invention, and in both of which the same designation of parts by letter reference is used.

Figure 1 shows in perspective an end view of a combined spring and springboard, and also showing the roller, roller-track, and rollerstops, the ends of the spring-board and spring being shown as broken off to illustrate only their operative parts in the combination that constitutes my invention, the application to each end of the spring -boards and springs being the same. Fig. 2 shows a longitudinal section taken through theroller, roller-track, roller-stops, and the end of the spring-board. The parts of the apparatus are designated by letter reference and their operation eX- plained as follows:

The letter S indicates the end of a metallic spring of the ordinary elliptical form used for such purposes, and (la flat under surface produced on the end of the spring.

The letter B designates the end of the springboard, which board is constructed of the usual form and adapted to be combined to operate in connection with the metal spring S to form a wagon-body support; and the letter R indicates a roller made with the flange ends a a. The letter T designates the roller-track, and M M stops on the end of the track. The roller R, between its end flanges, projects above the tops of the stops M M, and the flanges a a eugage with the vertical sides 0 of the track. The track T and stops M- M are preferably made of one piece of metal, and are secured firmly to the face of the board. The roller R, as thus constructed, is free to roll back and forth in the track between the stops. The flat surface (1 of the spring rests on the roller between the flanges, and as the spring is pressed down and extended laterally at the ends the latter move outwardly and inwardly on the rollers with an easy noiseless motion as this vibratory motion of the spring takes place. As the spring-board is also elastic and yields With the metallic spring under pressure, the roller device, being attached to the board, and as constructed, adapts itself to adj ust under the elastic action of both spring and spring-board.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination of the roller R, constructed with the end flanges, a a, the roller-track T, constructed with the end stops, M M, and ver- JAMES K. PQPINE.
